We have the server configured to preserve login sessions for 1 hour. The exact time seems to vary according to phase of the moon or something. But you shouldn't count on more than 1 hour. If you have "Keep me logged in" checked, then just revisiting or refreshing a board page should reactivate your session.

I've been getting this problem for at least 3 months now, but it only happens on my mobile Chrome browser (iphone). When it happens, I always get a warning message that I'm trying to go to a "bad" site. Then when it lets me in on the 2nd attempt, I have to log back in. It doesn't happen on my laptop browser, though. I think I actually made a thread about it a while back.

1) Problems accessing Chiff and Fipple. Site has been down many times and unable to access, up to about an hour. Often when finally accessing, I will need to login again...

I get this issue several times as well lately. About once a week this will happen

A quote from that thread;

Possibly a security/certificate issue. Many sites do not properly identify themselves as the site you're seeking, or are using an invalid or expired certificate. Can even be the difference between whether the URL uses www. in front of it or not.
